ESCAPE-GAS RECElVER.

SPECIFICATION forming part of Letters Patent N 0. 732,712, dated July 7, 1903.

Application filed September 20, 1902. Serial No. 124,252. (No model.)

useful Escape-Gas Receiver, of which the fol lowing is a specification.

The object of my invention is to providemeans for conducting gas escaping from underground mains to the open air and to prevent such escaped gas from following the pipes into cellars and basements or from accumulating in cavities along the line of the gas-main.

It is Well known that gas-mains are subject to various injuries producing leaks and that the gas thus escaping will often travel for some distance and will at times follow a branch house-pipe into a cellar and accumulate, occasionally causing disastrous explosions.

In the accompanying drawings, Figure l is a perspective view of my improvement applied to a gas-pipe. Fig. 2 is a vertical section of the same, the pipe to which the improvement is applied being shown inelevation. Fig. 3 is a detail view illustrating a slightlydifferent manner of connecting the receiver to the gas-pipe.

In carrying out my invention I employ a cylindrical casing A,'divided into two sections, lugs A being formed; on opposite sides of the casing on each'section and riveted together, as shown in Fig. 1. The upper sec-, tion has an openingat the top surrounded by an upwardly-extending annular flange A interiorly threaded. A sleeve B,exteriorly threaded at its lower end, fits into this flange. Secured to the upper part of the sleeve and extending above the same are the outwardlycurved arms B, supporting the downwardly open hood 13 the object of which is to shield the interior of the sleeve and casing from rain, snow, dirt, &c. Laterally the sides of the casing are apertured to permit passage of the gas pipe or main, the aperture at A being'of greater diameter than the exterior diameter of the pipe 0, and this aperture is sur- In Fig. 3 I have shown a modified construction in which the pipe is exteriorly threaded for a short distance, as at O, the .casing A "being in one piece and threaded onto the pipe, rendering the packing unnecessary.

In use the upper part of the sleeve B will extend above the surface of the ground or open into some upwardly open pit or chamber. Gas traveling along the exterior of the pipe 0 will enter the receiver through the funnel A and being prevented from continuing along the pipe and having means for easy egress to'the surface will pass up to the outer air through the sleeve B.

It will be readily seen that by placing adevice. of this kind on a pipe leading into a store or dwelling at'a point between the latter and the main, the funnel being toward the main, all danger of escaped gas traveling along the main passing'into or beneath the building is avoided, and these placed at various points along a main pipe-line will prevent accumulations of escaped gas atpoints along the line.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is]

A device of the kind described comprising a cylindrical casing perforated at each end, an outwardly-extending flange surrounding each perforation one'of said flanges being funnel-shaped,a gas-pipe passing through said perforations, a packing arranged-between the flange opposite the funnel-shaped flange and the gas-pipe, and an escapespipe leading from the top of the cylindrical casing.
